ABAP on HANA Optimization – Step by Step Remediation

1. STEP BY STEP TUNE YOUR CUSTOM ABAP CODE – HANAFIED

1.1 Introduction

Before Migrating to Suite on HANA or ABAP on HANA environment we need to analyse which of my ABAP code must be changed to avoid potential functional issues. In general existing ABAP code runs on SAP HANA as before
Only if ABAP code relies on technical specifics of the old database, ABAP code changes might be necessary.

Use Regular Expression to parse the image reference in the markdown sourcre code

As mentioned in my blog A Github repository issue backup tool developed by ABAP I am developing a tool in ABAP which can backup my github issues.

One of the functionality I would like to fulfill is to backup the images used in issue with markdown format as well. Take this issue of mine for example. This issue contains the reference to image files uploaded by me via dragging my local image files and drop them to the browser.

A Github repository issue backup tool developed by ABAP

I personally prefer to use Github repository issue to manage my knowledge. For issue, this is my github repository to store ABAP and SAP CRM related knowledge of mine and currently it has already 285 issues.

Step-by-step Guide to setup ABAP on HANA with Eclipse

Adding Custom Fields in WZR1,WZR2 and WZR3

Creating Additional Tab in WZR1/WZR2/WZR3

Now here is the document to show how to create an Additional Tab in WRZ1 (Settlement Request) screen. I did this as per my requirement which is for creating Payment Settlement Request.Here the data is coming from the IDOC to SAP server and to track the Payment Information the Settlement request is created and gets stored in the Standard WBRK table.

Now in this IDOC, it contains some IMP user specific data which needs to be stored ,it can be anything in my case it is  For Ex. IDOC number, IBAN number, SWIFT key and many more for which there is no fields provided in the Standard WBRK table. Now so as to store those values in WBRK table we need to create Custom Fields in WZR1 screen as well as in WBRK table.

Frist scenario is related to lines Items postings. The second scenario is related to  the error ‘balance in currency transaction.

Using the Rules Pattern to Improve Code Maintainability

The Root Cause

What is the root cause of all of this mayhem? In a word, unpredictability. It was impossible to gather all of the requirements at design time, and if working according to agile methodologies this would not even be attempted. Requirements evolve over time, new customers and business conditions come onboard, so even if the requirements analysis had been completely comprehensive at the beginning of the design process, new requirements would invariably crop up.
